Genes that increase plant oil and method for using the same

摘要

The object is to search for a transcription factor having a novel function selected from the function of increasing the plant body weight per plant individual, the function of increasing the weight of a specific plant tissue per plant individual and the function of increasing the productivity of a specific substance per plant individual, and to improve any one of the functions in a plant body. The plant body weight per plant individual, the weight of a specific plant tissue per plant individual, the productivity of a specific substance per plant individual, or the content of a specific substance per specific tissue in a plant body can be increased by expressing a transcription factor which is so modified as to have a reduced transcription-promoting activity.
